Paper Abstract

Molecular dynamics study of polyethylene extension is presented. The simulations were made using a model of a polyethylene globule containing 500 carbon and 1002 hydrogen atoms, which represents a small part of a bulk polymer specimen. The main objective of this work was to analyze the macromolecule structure evolution as well as to obtain stress- strain diagrams for the process. It is found that the stress- strain diagrams consist of three parts. The first part is due to deformation annealing, the second part is associated with work-hardening and the third one is connected with formation of an oriented structure. On the basis of the structure changes a molecular theory of deformation is suggested.
